Since 0.9.29 packages in the Lazarus directory are stored relative. Changing the
Lazarus directory will load the lpk files of the new Lazarus directory.
lpk files outside are used from the old positions.

Configs from another version are quietly loaded and updated.
Maybe a check could be added to warn if the environmentoptions.xml is from a
future Lazarus with two options: Quit and continue.

Yes.
